Join the power movement as a Quality Engineer

Commonwealth Fusion Systems (CFS) is looking for dedicated and highly motivated off-shift Quality Engineers to oversee manufacturing process quality for our HTS Magnet production and the SPARC Project. In this high-impact, hands-on role, you will take ownership of process stability and defect resolution on the production floor, ensuring our manufacturing processes yield reliable, first-of-a-kind hardware. You will partner closely with Manufacturing and Engineering teams to monitor process health, lead root cause investigations, and manage the end-to-end Non-Conformance Report (NCR) workflow. By implementing robust process controls and risk-informed corrective actions, you will resolve complex fabrication challenges and directly enable the SPARC project mission.

What you'll do:

• NCR Management & Defect Resolution:

• First-of-a-Kind (FOAK) Quality Monitoring:
• Monitor process health and hardware quality for low-volume, complex production. Collect and analyze discrete manufacturing data, focusing on defect trending, inspection results, and Measurement System Analysis (MSA) to ensure reliable measurements without relying on high-volume statistical methods
• On-Shift Quality Execution:
• Provide technical oversight and leadership for high-priority quality inspections during the off-shift. Execute established measurement and inspection methods to ensure all hardware strictly adheres to engineering requirements
• Manufacturing Instruction Refinement:
• Partner closely with Manufacturing and Engineering teams to refine detailed manufacturing instructions and Process Plans. Ensure that quality-critical characteristics are accurately documented, easily understood, and verifiable on the shop floor
• Supplier Quality Support:
• Support the supplier quality team by identifying and documenting supplier-related defects discovered during internal production, assisting with root cause data collection and action plans as needed

What we’re looking for:

• BS in Mechanical, Industrial, Material Science or Manufacturing Engineering
• Minimum 5 years of Engineering experience in a manufacturing, assembly or equipment manufacturing environment
• 1-2 years of Quality Engineering experience

• Excellent communication and organization skills

Bonus points for:

• GD&T and Metrology
• Knowledge of NDE (non-destructive evaluation) methods including dye penetrant, ultrasonic, computerized tomography, and x-ray
• Knowledge of cryogenics
• Minitab or JMP, MS Excel (including VBA), MS Visio
• Experience with assembly of large metallic components
• Experience with CMM or Romer Arm
• Experience with Welding Process and Nondestructive Testing

Must-have Requirements:

• Ability to occasionally lift up to 50 lbs
• Willingness to travel or work required nights/weekends/on-call occasionally
• Perform activities such as stooping, climbing, typing, standing, or sitting for extended periods of time
• Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
